Abstract: A fabrication method for a disposable article and a disposable article for absorbing liquids.This method consists in cutting an impermeable foil (35) so as to form two strips (35a) and (35b) in the median zone of said foil along a tracing of a sequence of equal straight-line segments parallel to the longitudinal axis of the foil and staggered alternatingly on either side of said axis. The strip (35a) is laterally shifted by a distance slightly less than the distance between the segments located on either side of the axis XX'. The strip (35b) follows a path which is longer than that of the strip (35a) by the repeat of the cut-out. The strips (35a) and (35b) then are deposited on the absorbing portions (34) in such a manner that the permeable zone is located in the central region of said portion.The obtained sheath is cut into individual articles.

Abstract: The invention relates to bleached cotton fibers and to absorbing materials for disposable articles. Its object is a process for shortening bleached cotton fibers consisting in(a) moving a fiber pad (1) between a trough-plate (2) and a feed roller (5) exerting a pressure between 0.3 and 0.6 MPa on the fiber pad,(b) pulling the fiber pad (1) beyond the trough-plate (2) bevelled at (9) so as to cut the long fibers constituting the fiber pad,(c) reconstituting the sheet.This process makes it possible to obtain fibers which can be used directly in diaper-making machines. The disposable articles so produced offer remarkable absorbing properties.

Abstract: A disposable diaper for incontinent adults comprising an absorbing pad covered by a liquid-impermeable external sheet (3) and a non-woven liquid-permeable inside sheet (4). This diaper is provided with four longitudinal folding lines, whereby it can be folded into several superposed levels (7a, 7b, 7c) when in the position of usage. Stretched elastic cords (13a) and (13b) are inserted between the sheets (3) and (4) near and parallel to the longitudinal edges. Prior to use two elastic belts (14a, 14b) are fixed on the same longitudinal edge (9a), one in the front zone (12) and the other in the rear zone (11) so as to clamp the cord (13a). The diaper has improved hermeticity and facilitates its emplacement by the user.

Abstract: The invention relates to liquid-absorbing products, in particular blood and urine. It concerns a salified acrylic allyloligosaccharide copolymer consisting in chemically combined form of at least one allyloligosaccharide with a mean degree of substitution of less than 4 per molecule and of at least one acrylic derivative with partly or totally salified carboxyl functions, said copolymer having a degree of retention, after 30 minutes in water salinated at 10 g/liter, exceeding 8 g of saline water per gram of copolymer.Preferably the allyloligosaccharide is allylsaccharose with DS 2 and the acrylic derivative is acrylic acid.The invention applies to using these polymers as additives to improve the absorption of absorbing materials used in personal hygiene.

Abstract: Curled non-woven material formed of waves such as contiguous anti-nodes (9,10) of adjacent waves consist of small adjacent pads (11,12) located on the same side of the median plan (8) of the non-woven material.Use: Medical and surgical compressesFIG. 3.

Abstract: Method for drying damp material by vapor recompression. The vapor (8) released by the damp material (4) circulating on the heating elements (2) of a vertical dryer is recompressed by means of a motor-compressor (9) so as to provide the heat-conveying fluid to the heating elements (2) of the dryer. Application to the drying of damp vegetables.

Abstract: Sanitary articles to absorb body liquids.They comprise an external liquid-impermeable sheet (2) enveloping the absorbing pad (1) not only across all of its surface (1b) opposite the human body and over all its thickness, but also it is applied as a pleat on the longitudinal edges of the pad side (1a) facing the human body.Menstrual napkins, pilches.

Abstract: Enzymes are immobilized on a solid support material containing essentially cellulose and lignin by a process involving oxidation of the support to provide aldehyde groups, amination of the oxidized support by reacting a diamine with the aldehyde groups, reduction of the aminated support to produce stabilized aminated groups, activation of the aminated groups by reacting the groups with a dialdehyde and immobilization of an enzyme by covalent coupling of the enzyme to the activated groups of the support. The enzyme may be invertase and the immobilized invertase can be used to treat a sugar syrup.
